Theoretical Research on Adjacent Multi-station Point Cloud Data Precision Combination in 3D Laser Scanning

Adjacent multi-station rotational scanning the target band with the 3D laser scanner ( Leica ScanStation II ) .acquires the 3D point cloud models of every rotational position. Adjacent multi-station point seriate cloud models have been registered, acquires the correspondent points. Then combines point cloud models with the theory of single strip aerial triangulation, acquires coordinates of cloud models in the same coordinate system, nonlinear correction to the model, excludes the cumulative errors caused by model combination, completes a high precision splicing of more stations continuous strip of point cloud model.
